WordPress.WP.AlternativeFunctions.curl_curl_errno
curl curl errno
The plugin uses raw cURL functions instead of the WordPress HTTP API.
Why It Shows Up
Plugin Check found `curl_*` calls in plugin code.
Why It Matters
The WordPress HTTP API handles transports, proxies, SSL behavior, filters, and host compatibility more consistently than raw cURL.
How to Fix
- Replace simple cURL requests with `wp_remote_get()` or `wp_remote_post()`.
- Handle `WP_Error`, status codes, timeouts, and response body parsing explicitly.
- If a bundled library uses cURL internally, keep it isolated and avoid passing unchecked user input into requests.
